Stema e Kastriotëve
The chronic of 18th September 1415 mentions as a customs official in Ishëm a person named Bozila from Kotorr. The customs in that time were given to the persons who paid more. But, this fact is important because it shows us that Kastriot had the customs system, something that proves the existence of the feudal state with all the structures and a cruise with the economics relations with the exterior world.
